PEEK Filled PTFE — Material Specifications, Engineering Data & OEM Supply
Produced at our Gujarat manufacturing works, PEEK Filled PTFE offers superior sealing and wear resistance for peek filled components. Combines virgin and reinforced PTFE fluoropolymer grades with precision compression moulding and 100% batch quality inspection for OEM applications.
Where PEEK Filled PTFE is used
Supplied as seats, seals and bushes for aggressive media at temperatures and loads above unfilled PTFE.
Selected where load and temperature exceed PTFE’s limit
high seating stress, continuous service near 250°C, and steam-sterilised equipment.
Chosen over Ekonol and glass grades when the duty is both chemically aggressive and hot: PEEK filler lifts the load and temperature ceiling while staying non-metallic.

Manufacturing process
Fabrication of PEEK Filled PTFE relies on high-tonnage powder compaction and free sintering of PTFE fluoropolymer. Preforms are pressed under strict pressure dwell parameters, then heat-treated above 342°C in forced-convection ovens to bond resin granules into a void-free, chemically resilient matrix.
Material selection notes
Physical performance of PEEK Filled PTFE is governed by high-grade PTFE fluoropolymer polymer formulation. Outstanding chemical resistance, high elongation (up to 400%), and low surface energy make it ideal for aggressive chemical pumps, valve seating, and pharmaceutical sanitary process lines.
How to specify your order
Procurement checklist for PEEK Filled PTFE: Specify outer dimensions (OD/ID/Length), chemical exposure media, temperature limits, and target delivery schedule. We assist in selecting the optimal virgin or filled material grade and provide itemized pricing with lead times.
Quality checks and inspection
Our quality department inspects PEEK Filled PTFE using precision coordinate measuring machines, digital surface roughness testers, and resin specific gravity balances, ensuring 100% adherence to customer drawing nominals.
Ordering and export documentation
Domestic PEEK Filled PTFE orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Material certificates and dimensional reports attached for qualified pharmaceutical and OEM shipments Contact info@hemsun.com or sales@hemsun.com with your PTFE components specification.
Export packing and lead time
Global shipments of PEEK Filled PTFE are handled by our dedicated export logistics team. Orders are packed in heavy-duty seaworthy packaging with VCI anti-corrosion barrier wrapping and dispatched with complete IEC customs documentation.
Storage and handling
Handling and assembly guidelines for PEEK Filled PTFE: Components should be kept in protective polybags until final assembly. Use clean, rounded assembly mandrels when installing over shaft threads to prevent surface scratches or edge nicking.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Filler content and sintered density are verified per ASTM D792 on each batch, with tensile and elongation checked per ASTM D4894. A mill test certificate stating the lot, filler content and measured values ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
